Why isn't ink ever used for drawing the origin in a chromatography experiment?

because the ink from the base line would mix with the ink blobs you are testing... its a bit obvious. and NEVER EVER draw your base line under the water. cause that would mean the blobs you are testing mix in the water and you dont know what colours the inks split into. depending on your age this is in your gcse and a level exams i think.

If you are to formulate your own theory about the origin of the universe how would you explain it?
The problem is - we can only speculate on the origin of the universe - based on our limited knowledge of the bit of space we live in ! There are literally billions of other galaxies out there - with hundreds of billions of suns and planets. There could be many other rules of physics & chemical elements that we just don't know of ! There's just no way of proving how the universe started (or whether this is the first ever universe !).
Explain why a control is needed in a valid experiment?
Because the scientific method means thinking of a hypothesis and proving a cause and effect in nature. If there is no control, then you can not prove the hypothesis of the cause and effect because you can not prove that your experiment caused the effect. If you have a theory that pepsi causes grass to grow, and with no control you manage to show that your lawn grew grass, how could you ever say that it was the pepsi that caused the growth unless your next door neighboors's yard died during the same time?

Why you use a control in an experiment?
The control is used as a base for comparison. The experiment needs a base before one can measure any changes to it, so the control acts as that base. You don't want to change the base. Ever. EVER!

Does scientific inquiry often begin by drawing a conclusion?
No... scientific inquiry begins by coming up with a question. From there you develop a hypothesis, test the hypothesis, alter your hypothesis if need be, test again, etc. Only after you have data that supports your hypothesis (if it ever does) do you draw any conclusions. If your data consistently does not support your hypothesis, no matter how it is modified, you may draw conclusions about your basic contentions as well. YES BUT..... what should you ask yourself in drawing a conclusion about an experiment?
